BOX-COVERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 643,804, dated February20, 1900.

Application filed May 13, 1898. Serial No. swear. on) model.)

To all whom it may concern.-

Be it known that we, ALBERT HUGH STE- vENsoN, residing at Manchester, inthe county of Lancaster, and NATHANIEL Borr CHAD- WICK, residing atStockport, in the county of Chester, England, subjects of the Queen ofGreat Britain, have invented certain new and useful Improvements inBox-Covering Machines, (for which we have made application for LettersPatent in Great Britain, No. 5,424, bearing date March 5, 1898,) ofwhich the following is a specification.

Our invention relates to improvements in what are known in the trade asbox-covering machines for applying atone operation a covering-strip ortwo or two or more covering-strips of paper, cloth, or other material toa paper or other box or lid. In such machines the box or lid to becovered is placed on a suitably-shaped form secured adjustably on ashaft driven by the machine. This form prior to our present inventionhas been secured in position by passing the threaded end of the shaftthrough a hole formed for its reception in the bottom of the hollowrectangular form and then applying a nut to the screwed end of theshaft. In this arrangement the screw is very apt to Work loose, and itis difficult, especially when the boxes tobe covered are all of smallsize, to get the hand, which is the left hand, inside the hollow form inorder to tighten or slacken the nut and also to adjust and set the formin order that the trimming and covering strips may be cut off at theproper point.

The object of our improvements is to overcome this defect, and weaccomplish this object in the manner and by the means hereinafterdescribed, with reference to the accompanying sheet of drawings, inwhich- Figure 1 is a side elevation of part of a boxcovering machine towhich our improvements are applied. Figs. 2 and 3 are details of partsof the same. Fig. i represents a section taken longitudinally of thehollow shaft.

In the views, a designates the frame or table of the machine, 1) theshaft from which the box-form c is rotated, and d the treadle forstarting and stopping the same.

According to our improvements we make the shaft e, on which the box-formc is secured, hollow, and on it at one end we form or fix a flanged boss6, and we secure the box-form c in position by passing through the holein it and through the hollow shaft e a bolt f, upon the threaded end ofwhich, projecting beyond the opposite end of the hollow shaft e, wescrew a milled nut g or a thumbscrew or other suitable device, which isput on and taken off, as required, by the right hand of the operator. Bythis arrangement we can readily put on or take off the boxform and asreadily adjust it in position without having to place the hand inside ofit and without any risk of spoiling a box through wrong adjustment ofthe form or through the form getting displaced on account of the nutworking loose.

Having now particularly described and ascertained the nature of our saidinvention and in what manner the same is to be performed,

we declare that what we claim, and desire to secure by Letters Patent ofthe United States,

In combination in a box-covering machine, the frame having bearings, ahollow shaft journaled in said bearings and having an extension providedwith a bearing end or head against which the bottom of the box may rest,said bearing end being arranged in position to hold the box in properrelation to the working parts of the machine, means for turning thehollow shaft, a bolt passing through the hollow shaft having a headthereon to clamp the bottom of the box between it and the bearing on theend of the hollow shaft, the opposite end of the bolt beingscrew-threaded and projecting from the hollow shaft and the nut fordrawing the bolt to clamp the box, substantially as described;

In witness whereof we have hereunto set our hands in presence of twowitnesses.
